Value Collection C703306 Hex Head Cap Screw 9/16-12

Product Description

The VALUE COLLECTION C703306 is a fully threaded hex head cap screw designed for heavy-duty fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel with no coating applied, this fastener delivers high tensile strength suitable for demanding load-bearing connections. The 9/16-12 thread size follows the Unified National Coarse (UNC) standard, and the 1-3/4-inch length under head provides consistent, reliable engagement. Conforming to ASME B18.2.1 and SAE J429 standards, this screw is a reliable choice for professionals who require traceability to recognized fastener specifications. Sold in a package quantity of 50.

This hex head cap screw is suited for use in heavy equipment maintenance, machinery assembly, structural steel connections, and general fabrication work. The fully threaded shank allows maximum thread engagement across the full grip length, making it appropriate for applications where clamping force must be distributed evenly. Machinists, millwrights, ironworkers, and maintenance technicians commonly specify Grade 8 fasteners for high-stress joints where standard Grade 5 hardware is insufficient.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician using a properly sized hex socket or wrench to avoid fastener damage. Always verify that the mating nut or tapped hole matches the 9/16-12 UNC thread specification before installation. Apply the appropriate torque value for Grade 8 fasteners as specified by the equipment manufacturer or applicable engineering standard. Inspect threads for damage or contamination before assembly.
